France Conducts Drone-Equipped Combat Cell Exercises During ORION 26 Drills
France Tests Drone-Armed Combat Cells in ORION 26 Drills
France’s 27th Mountain Infantry Brigade is utilizing the ORION 26 exercise to experiment with small, drone-armed combat cells, a strategic shift influenced by lessons learned from the conflict in Ukraine. The initiative was announced on April 18, 2026, with the objective of enhancing infantry mobility and reducing predictability on the battlefield.
Overview of the 27th Brigade’s Approach
The 27e BIM, based in Grenoble, is one of France’s leading mountain warfare units, comprising approximately 7,500 personnel across nine units. The brigade’s Chasseurs Alpins battalions are accustomed to operating in challenging terrains that require small-unit autonomy, making it an ideal candidate for this experimental approach.
The restructuring involves disassembling traditional platoons and sections to form “multi-arm micro-units.” Each unit is equipped with its own drones, a light vehicle, resilient communication systems, and the authority to make tactical decisions independently. This decentralization is crucial in modern combat scenarios where centralized command can hinder responsiveness.
The brigade has identified four key factors driving this transformation:
- The resurgence of high-intensity combat
- The persistent threat posed by drones
- The rapid engagement of targets
- The overwhelming presence of reconnaissance assets in the air
Significance of the ORION 26 Exercise
ORION 26 is the largest military exercise conducted by France since the Cold War, running from February 8 to April 30, 2026. It involves around 12,500 troops from 24 partner nations, 25 warships including the aircraft carrier Charles de Gaulle, approximately 140 aircraft, and 1,200 drones.
The exercise scenario simulates a threat reminiscent of Russian aggression, featuring a fictional expansionist state named Mercure targeting a neighboring country called Arnland. France leads a coalition to defend Arnland, transitioning from hybrid warfare to full-scale combat, which requires units to operate under contested conditions across various domains, including land, sea, air, cyber, and space.
For the 27th Brigade, the exercise serves as a critical test of decentralized combat strategies. Conducting these tests in an environment with active carrier aviation, electronic warfare, and numerous drones will determine the viability of their new doctrine.
Lessons from Ukraine and NATO’s Response
The conflict in Ukraine has highlighted the rapidity with which drone surveillance can detect and engage large vehicle formations. Both Ukrainian and Russian forces have learned that mass formations are increasingly vulnerable in modern combat. In response, the French military is adopting strategies similar to those being explored by other Western armies, focusing on smaller units, lighter vehicles, distributed authority, and continuous movement.
The 27e BIM’s operational methods in mountainous regions provide a foundation for applying these principles to conventional warfare, although it requires a significant shift in long-standing command practices within NATO forces.
France is not alone in this endeavor; the 13th Demi-Brigade of the Foreign Legion has tested single-operator drone swarms, while the 54th Artillery Regiment is experimenting with interceptor drones. French industry is also developing FPV drones in mobile micro-factories, indicating a comprehensive approach to modernizing military tactics.
Conclusion
The initiative by the 27th Brigade to restructure its combat cells around drone technology represents a significant shift in military strategy. This approach challenges traditional assumptions about battlefield visibility and command structures, as it empowers lower-ranking officers with the tools and authority to respond to threats in real-time.
The outcome of the ORION 26 exercise will provide valuable insights into the effectiveness of this new doctrine and its potential implications for the broader French Army and NATO forces.
